Keywords: Radiomics, Alzheimer's DiseaseAlzheimer's disease causes significant gray matter loss, which leads to changes in the brain surface's shape. In this work, we used the local gyrification index (LGI) and the three-dimensional tortuosity (𝜏3𝐷) to characterize the cortical morphology, and to determine if the obtained values were significantly different amog the Alzheimer's diagnosis. The subset of MRI studies was obtained from ADNI database. For the data analyzed, the results show that the 𝜏3𝐷 has a positive correlation with brain volume and can potentially be a biomarker for AD.
